What does link time Optimization do?

Link Time Optimization is a form of interprocedural optimization that is performed at the time of linking application code. Without LTO, Arm® Compiler for Linux compiles and optimizes each source file independently of one another, then links them to form the executable.

What is incremental linking?

Incremental linking links your exe/dll in a way which makes it easier for the linker to update the existing exe/dll when you make a small change and re-compile. So, incremental linking just makes it faster to compile and link your project.

What is MSIL module?

A managed program that does not have an assembly metadata in the manifest is called a module. If you compile with /c (Compile Without Linking) and /LN, specify /NOASSEMBLY (Create a MSIL Module) in the linker phase to create the output file.

What is lto linker?

Link Time Optimization (LTO) refers to program optimization during linking. The linker pulls all object files together and combines them into one program. The linker can see the whole of the program, and can therefore do whole-program analysis and optimization.

What is LTO rust?

LTO is an optimization technique that can perform whole-program analysis. It analyzes all of the bitcode from every library at once, and performs optimizations and code generation. rustc supports several forms of LTO: Fat LTO.

Should I enable link-time code generation (LTCG)?

I’ve heard that enabling Link-Time Code Generation (the /LTCG switch) can be a major optimization for large projects with lots of libraries to link together. My team is using it in the Release

When does the linker invoke link-time code generation?

The linker invokes link-time code generation if it’s passed a module that was compiled by using /GL or an MSIL module (see .netmodule Files as Linker Input ). If you don’t explicitly specify /LTCG when you pass /GL or MSIL modules to the linker, the linker eventually detects this situation and restarts the link by using /LTCG.

What happens if I don’t specify LTCG in the linker?

If you don’t explicitly specify /LTCG when you pass /GL or MSIL modules to the linker, the linker eventually detects this situation and restarts the link by using /LTCG. Explicitly specify /LTCG when you pass /GL and MSIL modules to the linker for the fastest possible build performance.
